How you prepare

By Mayo Clinic Staff

No special preparations are necessary for a standard transthoracic echocardiogram. You can eat, drink and take medications as you normally would.

Your doctor will ask you not to eat for a few hours beforehand if you're having a transesophageal or stress echocardiogram. If you have trouble swallowing, let your doctor know, as this may affect his or her decision to order a transesophageal echocardiogram.

If you'll be walking on a treadmill during a stress echocardiogram, wear comfortable shoes. If you're having a transesophageal echocardiogram, you won't be able to drive afterward because of the sedating medication you'll likely receive. Before you have your transesophageal echocardiogram, be sure to make arrangements to get home.
